Software
Every developer who has shipped software to other people has received this bug report: “It crashed sometime on the third floor, I think I’d just used the thing.” You can’t fix that. You can guess at it. You can ask follow-up questions the reporter has already forgotten the answers to. You can spend an afternoon […]

WebCalendar v1.9.22 adds MCP write and scheduling tools so AI agents can manage your calendar, a WordPress export page, 77 restored translations, an upgrade fix, and UI polish.
Software
If you’ve ever tried to run a busy calendar on WordPress, you’ve probably hit the wall. Most calendar plugins store every event as a WordPress post, and somewhere past a few hundred events the admin slows to a crawl — with the front end not far behind. For a small events page that’s fine. For […]

It didn’t save anything. It showed me the fully expanded recurrence (every occurrence, in my […]
Go
Years ago I wrote ILib, a small C library for reading, drawing on, and saving images. It has always been one of my favorite little projects — simple, dependency-light, and genuinely handy. Recently I ported it to Go as ilibgo, and along the way it picked up a few new tricks I’m excited to show […]
Basketball
It has been far too long since I’ve written about Virginia basketball — and honestly, so much has changed that I barely know where to start. Last time I really checked in, Tony Bennett was still patrolling the sideline and the Pack Line was gospel. Since then we’ve had a stunning retirement, a bumpy interim […]
Software
Here’s something I’ve wanted for a long time: asking my calendar questions in plain English. As of WebCalendar 1.9.16, you can. WebCalendar now ships an MCP server — Model Context Protocol support — so you can connect an AI assistant like Claude directly to your self-hosted calendar and say things like “What’s on my calendar […]
Software
A practical comparison of the best open-source, self-hosted Google Calendar alternatives in 2026 — Nextcloud, Radicale, Baikal, SOGo, DAViCal, and WebCalendar — and how to choose the right one.
WebCalendar
Serve your self-hosted WebCalendar over HTTPS by putting Caddy, Nginx, or Traefik in front of the Docker container — including the X-Forwarded-Proto fix that prevents redirect loops and mixed content.
WebCalendar

I’m excited to share my latest project: k5n-mcp-hub, a small, local-first hub for the MCP servers you build and run on your own machine. The code, docs, and a Dockerfile are on GitHub: https://github.com/craigk5n/k5n-mcp-hub The Model Context Protocol (MCP) has quickly become the way to connect AI assistants to tools, data, and services. If you […]
